Coach J

I have a Dometic rooftop ac/heat pump that will not stay running long enough to reach the desired temperature. It seems to be worse when temperatures outside are higher but that could be a pure coincidence example: I set the thermostat to 70 and it is 75 in the coach and the AC turns off. Not just the compressor but the entire unit. Back AC runs like a champ but front one has been having this issue for a while I think. When the compressor comes on it is blowing at about 22 degrees colder than intake temp but it just won’t stay running. any ideas??? thank you

As a matter of fact I went and checked and since the temperatures have cooled down it is working exactly like it should. It worked last night like it should. Seems the only issues are in the heat of the day so maybe it is overheating.

It will run like a champ on high so would you still think it’s possibly overheating? I did not have ladder access this weekend but i will get up top tomorrow and see. It just hs me stumped because the back ac runs just fine.

I have the exact same coach and all of a sudden my front zone 1 ac unit will not run long enough on auto to cool down near the desired temperature. Compressor and fan both come on and then cut off long before reaching desired temp. It seems to actually get to the desired temp at night when it’s cool but no where close during the warm part of the day. The zone 2 ac runs just fine and keeps the temp in the back where it is supposed to. My normal tech is coming out Friday and seems to think it’s a control board issue. Any thoughts.

Ok. It seems like I have a lot of questions but it’s all small things. I have a dual thermostat that runs 2 ACs. The back AC seems to run just fine with no issues. We have been on a trip since Thursday and Thursday-Friday we had no issues. No issues while technician was working on Rv most of the day Friday. When we packed up to come home we started noticing the front AC was not cooling properly on auto. Would not run or would come on and run for aboit 5 minutes then shut down. It would do this from time to time. last night and this morning it seemed to do just fine. Compressor would run and it would cycle to keep temp down to where we had it set. I set both AC at the same temperature just to see if they would cycle on and off about the same and they did for the most part as the day has gone on and the temperature has risen some. The back ac seems to be fine but the front ac now won’t stay on long enough to cool down to desired temp. I spoke to my normal mobile rv technician who I use for lost everything and he seems to think it’s a control board issue. I cannot get a definitive answer on the web for my exact issue. Most tall about single control issues. I am assuming if it were a thermostat issue it would be an issue with both ACs. Is my technician on the right track and if not any other thoughts. I have nO diagnostic tools with me and he is scheduled to come see me this week. I am just looking for some info because I trust this group. thanks Dometic AC

Yep. Mine does not have that

I thought maybe that too but there are none. I am sure I have missed something but I will keep looking to see what I can find

Last night I took a chance and pushed in the 2-20 amp pins. They did not stay in but it did reset the outlets I am assuming. I say that because that’s all I did and they started working. People asking about my gfci and me not understanding how they work , I am saying that there is no outlet in my coach that had a typical gfci plug. We have searched everywhere and have tried to find it in the owners manual with no luck. The outlet outside by the fridge doesn’t even have one and there isn’t one anywhere in the kitchen or bathroom where I would expected it to be. I guess I have no idea if pushing those pins fixed the outlets but that is all I did. I don’t know why they would not stay in like the 30 is but maybe you can shed light on that. I also have a concern that my house batteries may be draining while I drive and not charging but I don’t know that for certain. I had AC issues that seem to have been corrected somehow as well so I am just in a guessing mode. thank you as always for your input. Would be lost without this forum My point is there IS NO OULET in my coach that has a normal gfci. I am well aware of them and how they work and how to replace them. My point is there isn’t one.

I will look closer. My wife and I both looked and could not find one

There are 3 there a 50 and 2-20’s the 2-20’s seem to be tripped but when I push them in they done stay.

I am plugged to shore power and EVERYTHING in the coach works except the outlets. AC, lights, fridge, microwave, etc all work fine. Had an issue with the outlet in the bathroom this morning and it shut my generator down completely when it sparked. But after that I believe my outlets worked but I didn’t realize they were ALL out until we parked and hooked to shore power. They may have been running on generator I just didn’t check. there is no gfi outlet anywhere that I can find and I cannot find a tripped breaker. please help 2007 Monaco diplomat

I was just wondering if anyone could tell me how big of a job it is to repair floor damage from water. I know that is a very broad question but I’m just looking to decide if it’s a job I want to tackle or not. It seems to be a fairly small area just under a window but the wall is also soft. Unfortunately we bought the Rv and missed the floor issue. They had premier vinyl out down by the Rv dealer prior to their purchase and I cannot believe they put the vinyl over the damaged area but the people we purchased from only hs the rv a year so I double the damage is from that time. You never know with rv dealers. My concern is I am assuming it will ruin the flooring when I have to pull up the vinyl to repair the damaged area. Just looking for some thoughts befire I begin to decide what to do moving forward. I have an appointment at Talin rv for another repair and think I am going to ask them for their opinion also 2007 Monaco diplomat.

That is a great response. Thank you and I will talk to them about it.

Any idea what the cost of that repair may be and how in depth the process is? Also was your slide very far from closing or really close like mine? thanks

The flat I have an appointment for slide toppers with them. May ask if they could check that while I am there.

My flush slide when it’s in is about 1/4 of an inch from being completely closed futch in the upper right hand corner. It seems like it is a little further in at the bottom making the top not seal completely. The top left is flush but the top right is far enough out I can barely fit my finger in the open area. Any ideas? 2007 Monaco diplomat 40skq

Dometic. Will have to check model. Yes communication cables for duo therm Tstat

I know the connectors are reversed so to speak. When changing out the ends can someone clarify what I need to do as far as ensuring that I change these ends correctly? I have searched for a video but no luck. I am making an assumption that if I am careful when changing them and install the new connector in the same direction too As the old oneI should be correct. Just looking for clarification 2007 diplomat 40SKQ

Anyone have a resource for things like the food out table that comes in the 2007 diplomat 40SKQ? Mine is missing when I purchased also any chance to buy the sink covers for the kitchen sinks. They were missing as well. thanks

Ok. I think I am going to give it a shot. Thank you

So no issues with the slide outs not having enough clearance to go over the flooring?

Ok. So my floor was fixed and new vinyl put down less than a year ago with the previous owners. So there is no prep for me just to lay the floor. An you tell me if you did anything to measure and ensure there would be no slide out issues with the new floor.

Meaning a huge undertaking? Was that because of having to adjust slides, remove carpet or tile, etc? I ask because mine has already had all carpet and tile removed. It would be a simple lay down over nothing but vinyl. Just wondering what challenges you had

I messaged him. Thank you

I am looking at changing my Rv floor from vinyl (brand new) with laminate flooring. I have a 2007 diplomat 40SKQ. I am hoping someone on here has put laminate in this exact coach or there is an expert that can tell me if there are any issues , especially with slides, if I lay thin laminate wood. Thanks in advance
